Supergravity. Superdense. Possible tunnel to the other side of the Universe.

You really need to be a bit more specific with this question. Black Holes are condensed stars in which the escape velocity is higher than the speed of light. You might, for one, want to look up Hawking Radiation to get into black holes and the Second Law of Thermodynamics. Interestingly, it has recently been suggested and accepted that information can leave a black hole by means of quantum particle duality "stuff". The center of the Black Hole is what is known as a Singularity, in which the laws of physics predict their own violations. Kind of interesting.

Here are a few!
1. They aren't really black- they are just so heavy that they have lots of gravity! Light can't excape them, so you can't see them, which is why people call them black.
2. They destroy any information that goes into them.
3. I believe the only 2 true "properties" are something called "spin" and their mass.
Curiously point three means that they have a lot in common with elementary particles, and some people theorize that black holes are just huge "tiny" particles.
Read Brian Greene's "Elegant Universe". I am sure I have got some of this wrong, but his book is easy and fun to read, and explains black holes and relativity and all sorts of things with astonishing clarity.

the boundary of a black hole is called the event horizon because any event that occurs within, is invisible to outside observers.The black hole is invisible because nothing can escape from it. However, xrays emitted by heated matter entering the black hole can escape. So black holes are located by xray emissions

Its neither black nor a hole.

they do not allow the escape of any thing even light
